UT500 series Digital Megger Meter insulation testers measure the insulation resistance of electrical equipment and household appliances by measuring the insulation resistance between electrical circuits or between circuits and the ground. The UT500 series can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index), and DAR (Dielectric Absorption). These are ideal tools for ensuring transformers, generators, high-voltage motors, capacitors, cables, arresters, and other electrical equipment can operate safely and accurately. Uni-T Digital Megger Meter Insulation Tester UT502A 2500V AC Voltmeter Megohmmeter High Voltage / Overload Indicator LCD Backlight.

• 2000-count LCD, overload indication, backlight
• AC voltage measurement, auto power off
• Auto discharge
• Continuous low resistance measurement
• Continuous measurements mode, red warning light, and buzzer function
• PI and DAR measurement, auto resistivity calculation
• Low resistance returning to zero function to improve accuracy
